Specication of Letters Patent.

To all whom it may concern Be it known that I, JOHN It. ROGERS, acitizen of the United States, residing at Brooklyn, in the county ofKings and btatev of New York, have invented certain new and usefulImprovements in Typographical Machines, of which the following is aspeciication, reference being Ahad therein to the accompanying drawing.

My invention relates to, typographical machines, such as linotypemachines of the general organization represented in Letters. Patent ofthe United States No. 436,532, to O. Mei'genthaler, wherein circulatingmatrices are 'released from a magazine in the order in which theircharacters are to appear in print and then assembled in line,- thecomposed line transferred to the face of a mold, the mold filled withmolten metal to form a slug or which produce the type charactersthereon, and the matrices thereafter elevated and returned through adistributingmechanism to the magazinefroin which they started.

More particularly,.`t relates to that vclass of machines in which areemployed type or matrices provided' with two or more superposedcharacters, and devices` by which the' vertical position of the type ormatrices in .the composed line may be varied so that f each will presentone or another of its characters in operative position, as demanded. Thematrices when thus assembled at different levels are carried in thisconditionA to the casting mechanism, and are subsequently brought to acommon level preparatory to' distribution. Various mechanisms have beenemployed to eect the leveling of the matrices, one form being shownv andde- Letters Patent No.

cip ally with present invention is concerned printhis method of levelingand aims to secure the same result in a simplified and convenientmanner. As is well known, the first elevator is ordinarily provided atAits open end with a pair of retaining pawls which engage behind thelast matrix inthe linotype against the matrices ledges- B1 andf B2,

Specifically, I propose to construct these retaining pawls of such formthat theyi'notfv only serve tohold the line within the ele-A vator, lbutin addition act upon the matrices as they are transferred therefrom .andbring them toa commonlevel.

In the accompanying drawing, I have vshown my invention in preferredform and by way of example andas applied to a linotype machine, butobviously many changes and variations may be made therein, .and in itsmode of application, comprised within its spirit. f y. ,Y

Generally speaking, I desire itto be understood that I do not limitmyselfto any specific form or embodiment, except in so far which win Sau`a; i

as such limitations are specified in the claims.

Referringto the drawing: ligurey l is a front elevation, partly brokenaway, ofthe first ,elevator and 'intermediate channel of, 'a

linotype machine, having my invention applied thereto; ing the first tothe second elevator in operativev relation elevator; Fig. 3 is asectionon Fig. 2 is a similarv View show- Y* the line 3--3 of Fig."2; and Fig.4 is adetail-view.

In the accompanying drawing, I have shown only such parts of the machineas are necessary to an understanding of my invention. `The other partsmay be of usual` construction, such as illustrated in the MergenthalerPatent No. 436,532, before referred to, or as embodied in the commerciallinotype machine.

The type or matrices X after being composed in line are transferredthrough the intermediate channel A to the first elevator B, which,afterpresenting them tothecasting mechanism, rises to the position shown inFig; 2, when the matrices are moved from the elevator by the transferdevice or pusher C into the upper transfer channel F and onto thetoothed bar D1 of thesecond elevator D, whichthen carries them upwardfor distribution into their roper magazine, all in the usual way. Reerring to, Fig. l, it will be noted thatthe intermediatechannel A isformed with ledges A1' and A2, and that the first elevator B is alsoformed with the latter ledges registering with the former, when theparts are in esi - the pawls and move them vertxcally. Since,

however, I propose to rely uponthe lnclined surfacestEHtodepresstheelev'ated matrices transfer through'the machine. The ledges-A1 and B1L engage beneaththe upper ears of" l n l tegame i the positionshown, so as' to provide vcon-. f-

tinuous tracks upon which the matrices may be supported at differentlevels in their the matrices standing' atthe lower level,

while the ledges A2 and B2 engage beneath the lower ears ofthe'matr'ices standing at the upper level. Similarly, the upper trans-yfer channel F is formed with ledgesl F1 adapted tov register with theupper ledgesL B1 of the first elevator, when' the Ylatter occupies theposition s howninFig, 2, so as to providea continuous lsupporting trackfor` vthe matrices as they are transferred from the elevator 4ontoth'e'toothed barD1.v

.. -a pair of 'pa'wlsy E, which are located .in re- -In accordancewithfmy invention, the 'first elevator B is providedat-itsopen end 'withcesses B3 in thev side walls of the elevator and are pivotally mountedupon transverse studs E so as to' be movable-vertically., Ar-l. rangedbeneath the rear ends of the pawlsf,

l `are. springs E3 tending to lower their'for'- ..ward ends totheposition shown in- Fig 4',

pins E4 fixed to-the walls of theelevator actclined surfaces E1 toengagebehind the lastv ing to arrest the pawls in this position. vThe forwardportions ofthe pawls are, offset, as.

at E (see Fig. 3) so asto'overlie the matri'ces, and are formed withinwardly 1nmatrixain thev comp'osedline andhold it in Vaa' proper'position (see Fig, 4.).. The forward portions' of the pawls are'alsoAformed lwith outwardly inclined surfaces E2, ".vhich'a're adapted to beengaged by the matrices as they vare transferred intovthe first elevator"from the intermediate channel,` and@V thus ,cause thepawls to movevertically (as shovvny by dotted lines in Fig. l) against theyactioir-"of theirspiingslil8 and'permit the passage'. of the-matricesthereunder.` Similarly, when I' the matricesfa're transferred fromth`e`first" elevator into the, upper transfer channel F,

' .G located in the fixed framework and )having y '-55 a. p air ofprongsG1 to project into the` re# they will engage the inclined surfaces ll oftothe -leve1 of the lower ones during their transfer `from the elevator,means 'are provided to limit the upward movement of the- 'awls at suchtime In the'present instance, enploy for this purpose a forl edmembercesses B3v of the elevator-when the*P latter arrives at its uppermostlposition and arranged to be engaged'bythepawls asthey.

' are elevated by' the matrices'during their transfer fromthe elevator'(see Fig. The 'operation of the parts will j now be clear. Vhen thefirst elevator B isqempty and in receiving relation to the intermedi atechannel fr, the pawls occupy the position shown. fr. A s the composedlineis' transferred into the elevatongthe matn rices engage the inclinedsurface E2 of the pawls and lift them against the action of theirsprings E3, the extent of such lifting being governed by theconstitution of the Icomposed line, that is to say,'accordinggto whetherthe matrices all stand at the same levelv or at different levelstherein. If the matrices all stand atthe same level, then after thecomposed line enters the elevator;

thepawls are imm'ediately'returned,to their original position (as shownin Figl) with their inclined surfaces El engaging behind theflastanatriit in the line. If,.however, the last' matrix. in thecomposedline is standing atthe upper level, thepawls will occupy the positionsho-wn by full 'lines in Fig. l.

The vfirst elevator BI now descends to pre-y sent the linej to thecasting mechanism and subsequently ascends to carry it intoregistryfwiththe lupper transfer channel F, at whiclr timer-the transferdevice C moves it from the elevator-into-the channel. During `suchtransfer, kmatrices standing at the lower level,engagethe-inclinedsurfaces E? of the pawlsa'nd'merely raise them sufficiently to permittheir passagey thereby. However, any matrices'standingfat the,upperflevel tend to lift-the pawls to agreater extent, but this vtendency is resisted and overcome by the engagement of the .pawls withthe prongs Gf of the fork G, thepawls being thus maintained in asubstantially rigid condition and -in such position that their inclinedsurfaces YE1 engage the elevated matrices, as they are successively Aslidv vofi' their sustaining ledge B?, and positively depress them tothe -level of the lower matrices, when they may vpasstherewithalongtheledges'F1 of the upperftransfer channelF andonto the toothed bar D? ofthe second elevator D.

(See Figs. 2 a'nd.)

It will be understood that while' I have designed thelpawlsl E tosubserve the two `functions noted, they may `be employed to perform one.or another thereof lndependently, as it willbe. apparent'th'at theyymay be used advantageously for either purpose` .depending, upon thestyle 'offmachine to which `they are applied. l v -f Aspreviouslystated, I ha-vefshown my invention merely in preferred 'form-and by way'of example and it will be obvious `that many modifications andalterations therein,-

and in its mode of application, will suggest lle 12e' 4`themselves tothose' skilled in the art with# i levels therein, a device to vtransferthem lac therefrom, and a movable member carried by the elevator andhaving an inclined surface to engage the type or matrices during theirtransfer therefrom and bring them to a common level, the said memberbeing provided withg an oppositely inclined surface which is engaged bythe type or matrices as they enter the elevator and thus displacedthereby. y I
